Advertising an item that one does not have possession off
Q:
1. Say I place advertisements for commodities that I do not have possession of. The advert will not mention that I do not currently possess such items. Anyone seeing the advert the will be given the impression that I do possess such items, but no lie/deception will take place. Then when customers contact regarding these products I will take down their orders, but not take payment. Only once I purchase and physically possess these items from my supplier, I will then contact the customers regarding payment. Is this manner of advertising commodities that I do not have possession of permissible?
2. After paying the supplier for the product, the supplier sends it to me via a courier company. Whilst this product is still travelling to me across the country in the possession of the courier company, but nevertheless after I have paid for the product, can I sell such a product to a customer?
